- Abstract
- Methods are described in this study to predict the magnetic configuration at the saddle point in nanostructured cells of single magnetic thin films and synthetic antiferromagnets. The prediction is done indirectly by calculating the self-demagnetizing field at the saddle point, which is then compared with the value calculated under the ideal single domain state. The saddle point magnetic configuration in the single magnetic thin films deviates more from the ideal single domain state than in the synthetic antiferromagnets. As the cell geometry varies from rectangle to ellipse, the deviation decreases monotonically in the single magnetic thin films, while it remains nearly constant in the synthetic antiferromagnets.
